Bed lift mounting member

ABSTRACT

A structure such as a recreational vehicle includes a guide member coupled to a wall of the structure, a carriage member slidingly coupled to the guide member, a mounting bracket coupled to the carriage member, and a bed coupled to the mounting bracket. The mounting bracket can be coupled to the carriage member in a readily releasable manner. The mounting bracket can also be slidably received by a bed support member that is coupled to or part of the bed.

BACKGROUND

Shelter from the elements is a basic human need. Over the years, anumber of structures have been developed to satisfy this need. Forexample, structures such as homes, apartments, condominiums, and thelike have been used to effectively provide shelter from the elements. Inaddition to these immobile structures, mobile structures such as landvehicles, aircraft, watercraft, and the like have also been used toeffectively shelter and/or transport people. Many of these structuresare used not just to provide shelter but also to provide livingquarters.

Ever since people began to use structures as living quarters, there hasbeen an almost universal desire to increase the size and comfortprovided by these structures. This is true regardless of whether thestructure is mobile or immobile. For immobile structures, this desire ismanifest by the continually increasing size of homes, apartments,condominiums, hotels, and the like. In the context of mobile structures,the desire for more space and comfort is manifest by the increased sizeof land vehicles, aircraft, watercraft, and the like.

The size of immobile structures is often limited by factors such ascost, available real estate in the area, government regulations, and thelike. The size of mobile structures is often limited by transportationregulations set by the government (e.g., width of a road vehicle, lengthof a road vehicle, etc.) and by the physical dimensions of the roads(e.g., width of a travel lane, distance between railroad tracks, heightof bridges, etc.) or other medium of transportation (e.g., waterways,etc.). Moreover, building larger structures unnecessarily increases theconsumption of valuable resources (e.g., land, steel, wood, etc.).Accordingly, it would be desirable to more effectively utilize the spacein structures without increasing the “footprint” of the structures.

One type of vehicle where it is especially desirable to maximize theutility of the interior space is a “toy hauler” type recreationalvehicle. A toy hauler is a recreational vehicle having a cargo area usedto receive and transport off-road vehicles. Bed lifts have beendeveloped for the cargo area of toy haulers as shown in the '545 patent.

Certain off-road vehicles have trouble fitting under beds lifted byconventional bed lifts. This is especially a problem for side-by-sideoff-road vehicles such as the Polaris RZR and the like, which have highroll bars. Other off-road vehicles may not be able to fit inside thecargo area because the wheels of the off-road vehicles hit the bed liftcomponents attached to the wall near the floor. The bed lift componentscan be raised relative to the floor but this also raises the bed makingit difficult to get in and out of bed or sit on the bed when it is in aseating configuration.

SUMMARY

A number of representative embodiments are provided to illustrate thevarious features, characteristics, and advantages of the disclosedsubject matter. The embodiments are described in the context of bed liftsystems for toy haulers. It should be understood, however, that many ofthe concepts may be used in a variety of other settings, situations, andconfigurations. For example, the features, characteristics, advantages,etc., of one embodiment can be used alone or in various combinations andsub-combinations with one another.

A structure includes a bed that moves between a lowered position wherethe bed is positioned to receive one or more persons to sleep thereonand a raised position where the bed is stowed adjacent to the ceiling ofthe vehicle. In one embodiment, the structure is a vehicle such as a toyhauler recreational vehicle.

In one embodiment, the bed can move between the lowered position wherethe bed is oriented horizontally, the raised position where the bed isalso oriented horizontally, and an upright position where at least aportion of the bed is oriented vertically and stowed adjacent to a wallof the structure. Moving the bed to the upright position increases theavailable height in the area where the bed is located. For example, atoy hauler can hold and transport a taller off-road vehicle in the cargoarea when the bed is in the upright position.

In another embodiment, the bed can be configured to move between asleeping configuration where the bed is flat and a seating configurationwhere the bed forms one or more seating units which each include a seatbase and a seat back. The seating configuration can include at least twoseating units facing each other and separated by an aisle. When the bedis in the upright position, the portion of the bed that forms one of theseating units is stowed vertically adjacent to one wall of the vehicleand the portion that forms another one of the seating units is stowedvertically adjacent to an opposite wall of the vehicle.

In another embodiment, the structure can also include a second bedpositioned above the first bed. The second bed can move between alowered position where it is positioned to receive one or more personsto sleep on it and a raised position where it is stowed adjacent to theceiling of the structure.

In another embodiment, the structure includes a bed lift system insidethe structure that moves the bed between the lowered position, theraised position, and the upright position. The bed lift system caninclude a mounting member coupled to the bed. The mounting member canmove between a first position where the bed is oriented horizontally anda second position where the bed is oriented vertically. This allows thebed to rotate between being horizontal and being vertical.

In another embodiment, the mounting member can include a support basecoupled to the other components of the bed lift system and a support armcoupled to the bed. The support arm rotates relative to the support baseto move the mounting member between the first position and the secondposition.

In another embodiment, the bed lift system can comprise a liftingassembly including a guide member coupled to the vehicle, a movingmember coupled to the guide member in a manner that allows the movingmember to move vertically relative to the guide member, and a mountingmember coupled to the moving member. The mounting member can support thebed at a location that is: (a) below the lowest point where the mountingmember is coupled to the moving member or (b) below the bottom of theguide member.

In another embodiment, the bed lift system includes a mounting memberthat is supported against the wall of the structure. For example, themounting member can include an upper portion where the mounting memberis coupled to the other components of the bed lift system and a lowerportion that bears against the wall. The lower portion of the mountingmember is supported by the wall so that it can't rotate towards the wallwhen weight is put on the bed. However, the mounting member can extendbelow the other components of the bed lift system

This allows the wall-mounted components of the bed lift system to bepositioned higher on the wall so that they do not interfere with thingslike the tires of the off-road vehicles. The mounting member isvertically offset so that it can extend below the other components whenthe bed is in the lowered position so that the bed is at the desiredheight.

The Summary is provided to introduce a selection of concepts in asimplified form that are further described below in the DetailedDescription. The Summary and the Background are not intended to identifykey concepts or essential aspects of the disclosed subject matter, norshould they be used to constrict or limit the scope of the claims. Forexample, the scope of the claims should not be limited based on whetherthe recited subject matter includes any or all aspects noted in theSummary and/or addresses any of the issues described in the Background.

It should also be appreciated that any of the new subject matterdisclosed in this document can be used with any of the embodimentsdisclosed in the '545 patent. For example, the beds 640, 641 can move inthe manners disclosed in this document using any of the lift systems inthe '545 patent. Also, any of the mounting members disclosed in thisdocument can be used with any of the embodiments in the '545 patent. Thenumber of embodiments that can be created by the various combinations isvirtually limitless.

The bed lift system 12 includes lifting assemblies 630 a, 630 b, 630 c,630 d (collectively or generically referred to as “lifting assemblies630”), a drive member 634, cross members 614, and a motor assembly 636.The lifting assemblies 630 a, 630 c are coupled to the first side wall16, and the lifting assemblies 630 b, 630 d are coupled to the secondside wall 18.

A cross member 614 is coupled between the lifting assemblies 630 a, 630c and the lifting assemblies 630 b, 630 d. The cross members 614 conceala flexible drive member that synchronizes movement of the adjacentlifting assemblies 630 a, 630 c and 630 b, 630 d. The drive member 634synchronizes movement of the pair of lifting assemblies 630 a, 630 ccoupled to the first side wall 16 and the pair of lifting assemblies 630b, 630 d coupled to the second side wall 18. The motor assembly 636drives movement of the lifting assemblies 630.

The lifting assemblies 630 vertically move a first or lower bed 640 anda second or upper bed 641 between a lowered position the beds 640, 641are oriented horizontally and positioned to receive one or more personsto sleep thereon (FIGS. 2 and 27) and a raised position where the beds640, 641 are oriented horizontally and stowed adjacent to the ceiling 24of the vehicle 10 (FIGS. 3 and 28). It should be appreciated thatalthough two beds 640, 641 are shown in the Figs., the liftingassemblies 630 can lift one bed 640 or more than two beds.

In one embodiment, the lifting assemblies 630 can reciprocally and atleast translationally move the beds 640, 641 between the loweredposition and the raised position. Translational movement refers tomotion of a body where every point of the body moves parallel to and thesame distance as every other point of the body.

Referring to FIG. 31, each lifting assembly 630 includes a lower movingassembly 650, an upper moving assembly 651, and a guide assembly 660.The moving assembly 650 is coupled to the lower bed 640 and the movingassembly 651 is coupled to the upper bed 641. The moving assemblies 650,651 cooperate with the guide assembly 660 to vertically move the beds640, 641 between the lowered position and the raised position. In oneembodiment, the moving assemblies 650, 651 slidably cooperate with theguide assembly 660 to vertically move the beds 640, 641.

The moving assemblies 650, 651 each include a moving member or carriagemember 1920, 1620, 1622 and a mounting member 1940, 1840, 1941 coupledto the moving member 1920, 1620, 1622. The mounting member canalternatively be referred to as a bracket, mounting bracket, mountingdevice, mounting mechanism, or mounting assembly. It should beappreciated that the moving assemblies 650, 651 can include anyembodiment of the moving member 1920, 1620, 1622 and any embodiment ofthe mounting member 1940, 1840, 1941.

It should also be appreciated that the moving assemblies 650, 651 caninclude any of the embodiments of the moving member and/or mountingmember disclosed in the '545 patent. For example, the moving assemblies650, 651 can include the moving members 620, 622 and the mounting member840 disclosed in the '545 patent.

The guide assembly 660 includes a guide member or guide rail 618 coupledto one of the walls 16, 18 of the vehicle 10 in a vertical orientation.The moving members 1920, 1620, 1622 are coupled to the guide member 618in a manner that allows them to move vertically relative to the guidemember 618. In one embodiment, the guide member 618 defines a channelsized to slidably receive the moving members 1920, 1620, 1622. Forexample, the guide member 618 can have a C-shaped cross section thatforms the channel and slidably receives the moving members 1920, 1620.

The moving assemblies 650, 651 support the beds 640, 641, respectively,as the beds 640, 641 move vertically. The mounting members 1940, 1840,1941 are coupled to beds 640, 641. The mounting members 1940, 1840, 1941are, in turn, coupled to the moving members 1920, 1620, 1622.

Referring to FIGS. 2-6, the lower bed 640 is coupled to the liftingassemblies 630 by the moving member 1920 and the mounting member 1940.The upper bed 641 is coupled to the lifting assemblies 630 by the movingmember 1920 and the mounting member 1941. The main difference betweenthe mounting members 1940, 1941 is that the mounting member 1940 movesbetween a first position where the bed is oriented horizontally and asecond position where the bed is oriented vertically and the mountingmember 1941 is stationary.

FIGS. 2-6 illustrate the different bed/couch configurations that can beachieved using the bed lift system 12. The beds 640, 641 can movebetween a lowered position where the beds 640, 641 are orientedhorizontally and positioned to receive one or more persons to sleepthereon (FIG. 2) and a raised position where the beds 640, 641 areoriented horizontally and stowed adjacent to the ceiling 24 of thevehicle 10 (FIG. 3).

The beds 640, 641 can also move between the lowered position, the raisedposition, and an upright position where at least a portion of the lowerbed 640 is oriented vertically and stowed adjacent to the walls 16, 18of the vehicle 10 (FIG. 4). The upright position is particularly usefulwhen it is desirable to provide additional overhead clearance inside thevehicle 10 to accommodate tall off-road vehicles and the like.

In the embodiment shown in FIG. 4, the lower bed 640 is divided roughlydown the middle into a first portion 1970 and a second portion 1972. Theportions 1970, 1972 of the lower bed 640 rotate downward from the raisedposition to the upright position (FIGS. 4, 39, and 41) where theportions 1970, 1972 are oriented vertically and stowed adjacent to thewalls 16, 18, respectively, of the vehicle 10. In an alternativeembodiment, the portions 1970, 1972 can rotate upward from the loweredposition to the upright position (FIGS. 39-40).

It should be appreciated that the bed lift system 12 can include anynumber of configurations for the lower bed 640 when it is in the uprightposition. For example, the lower bed 640 can be a single unitarycomponent that rotates to a vertical orientation adjacent to one of thewalls 16, 18 in the upright position (FIGS. 36-38). In other words, theentire lower bed 640 rotates to a vertical, stowed position adjacent toone of the walls 16, 18.

The beds 640, 641 can also move between the lowered position, the raisedposition, the upright position, and a partially stowed position wherethe lower bed 640 is oriented horizontally and positioned to receive oneor more persons to sleep thereon and the upper bed 641 is orientedhorizontally and stowed adjacent to the ceiling 24 of the vehicle 10(FIG. 5). The partially stowed position can be useful in situationswhere the user wants to use the lower bed 640 but doesn't want to usethe upper bed 641.

There may be situations when the user wants additional seating spaceinside the vehicle 10. This can be accomplished by configuring the lowerbed 640 to move between a sleeping configuration where the bed 640 is atleast substantially flat to receive one or more persons to sleep thereonand a seating configuration where the bed 640 includes a seat base 1974and a seat back 1976 to receive one or more persons to sit thereon (FIG.6).

In one embodiment, the lower bed 640 forms at least two seating unitswhen the bed 640 is in the seating configuration. For example, theportions 1970, 1972 of the lower bed 640 can be roll-over sofas thateach convert into a seating unit that extends adjacent to and parallelwith the walls 16, 18, respectively, of the vehicle 10 (FIG. 6). In thisconfiguration, the seating units face each other and are separated by anaisle that is parallel to the lengthwise direction of the vehicle 10.

The mounting member 1940 and moving member 1920 are shown in greaterdetails in FIGS. 7-15. The mounting member 1940 is coupled to the lowerbed 640 and makes it possible for it to move to the upright position. Asmentioned above, the mounting member 1940 can move between a firstposition where the bed 640 is oriented horizontally and a secondposition where the bed 640 is oriented vertically, preferably adjacentto one or more of the walls 16, 18 of the vehicle 10.

FIGS. 7-10 show the mounting member 1940 with all of the fasteners inplace. FIGS. 11-14 show the same views with the fasteners removed tobetter illustrate the structure and design of the mounting member 1940.

The mounting member 1940 includes a support arm or first support member1942 movably coupled to a support base or second support member 1944.The support arm 1942 extends underneath and is coupled to the lower bed640. The support base 1944 is coupled to the moving member 1920.

In one embodiment, the mounting member 1940 is coupled to the movingmember 1920 in a readily releasable manner. The mounting member 1940includes projections, tabs, or hooks 1943 that fit in correspondingopenings or holes 1945 in the moving member 1920. The mounting member1940 is coupled to the moving member 1920 by inserting the projections1943 into the holes 1945 and moving the mounting member 1920 downwardinto a snug fit. The holes 1945 can be tapered in the manner shown inFIG. 15 to more securely receive the projections 1943. Thisconfiguration makes it easy to couple and decouple the mounting member1940 from the moving member 1920.

The support arm 1942 is rotatably coupled to the support base 1944. Thisallows the support arm 1942 to move between a first position where thesupport arm 1942 extends horizontally from the support base 1944 and asecond position where the support arm 1942 extends downwardly from thesupport base 1944.

The support arm 1942 is coupled to the support base 1944 by a fastener1947, which extends through a slot or opening 1948 in the support arm1942 and a corresponding hole or opening 1946 in the support base 1944.The support arm 1942 rotates on the axis of the fastener 1947 to movebetween the first position and the second position.

The support arm 1942 includes a projection, lug, or support element 1950that engages a corresponding recess 1952 in the support base 1944 tohold mounting member 1940 in the first position. Gravity holds theprojection 1950 in the recess 1952 to create an interlocking arrangementthat prevents the support arm 1942 from rotating downward relative tothe support base 1944. In one embodiment, the projection 1950 is a pincoupled to the support arm 1942 by welding or the like.

A fastener or locking member 1949 locks extends through correspondingholes 1954, 1956 in the support arm 1942 and the support base 1944,respectively, to lock the support arm 1942 and support base 1944together. The support arm 1942 is unable to rotate relative to thesupport base 1944 when the fastener 1949 is in place.

The fastener 1949 can be any suitable fastener that is capable ofextending through the holes 1954, 1956. Preferably, the fastener 1949doesn't include threads thereby making it easier to fasten and release.In one embodiment, the fastener 1949 is a pin that extends through theholes 1954, 1956.

The support arm 1942 rotates from the first position to the secondposition in the manner shown in FIGS. 16-20. The first step is to removethe fastener 1949 from the holes 1954, 1956 so that the support arm 1942is capable of moving upward relative to the support base 1944. Thesupport arm 1942 cannot move downward because the projection 1950 isengaged with the recess 1952.

The support arm 1942 is rotated slightly upward to disengage theprojection 1950 from the recess 1952. The support arm 1942 is then movedtranslationally in a longitudinal direction outward from the fastener1947 until the projection 1950 clears the outer edge of the support base1944. The slot 1948 makes it possible for the support arm 1942 to move ashort distance translationally relative to the fastener 1947. Thesupport arm 1942 is in the position shown in FIGS. 16-17.

The projection 1950 is beyond the outer edge of the support base 1944and free to rotate in the manner shown in FIG. 18. The support arm 1942pivots downward until it is roughly vertical as shown in FIGS. 19-20.

It should be noted that the support arm 1942 can be moved from thehorizontal position to the vertical position without loosening orremoving a threaded fastener such as a bolt or screw. This makes itpossible for the user to move the bed 640 between a horizontalorientation and a vertical orientation without tools.

It should also be noted that the support arm 1942 moves through apredefined sequence of movements as it moves from the horizontalposition to the vertical position. The support arm 1942 rotates upward,moves outward translationally, and rotates downward. The configurationof the support arm 1942 which allows the projection 1950 to engage therecess 1952 and remain in place by the force of gravity produces thistype of movement.

Referring to FIGS. 19-20, the support arm 1942 can be locked in thevertical or stowed position by placing the fastener 1949 through thehole 1956 in the support base 1944. The support arm 1942 and the supportbase 1944 are shaped so that the support arm 1942 cannot pivot upwardwhen the fastener 1949 is positioned in the hole 1956. In this manner,the same hole 1956 in the support base 1944 can be used to hold thesupport arm 1942 in the horizontal or vertical position.

FIGS. 21-24 show an embodiment where the lower bed 640 can be easilyremoved from the lifting assembly 630. In this embodiment, a bed supportmember or bed support bracket 1960 is coupled to the underside of thelower bed 640 and configured to receive the support arm 1942.

The bed support member 1960 is coupled to the underside of the lower bed640 in the manner shown in FIG. 21. The bed support member 1960 includesa channel 1962 that is shaped to slidingly receive the support arm 1942.In the embodiment shown in the Figs., the support arm 1942 has aninverted L shape and the bed support member 1960 has an upright L shape.The two components slide together so that the horizontal portion of theLs are adjacent to each other and prevent the lower bed 640 from comingoff the support arm 1942.

The lower bed 640 is locked in place using a fastener or pin thatextends through a hole 1964 at the distal end of the support arm 1942.The support arm 1942 extends slightly beyond the end of the bed supportmember 1960 so that the fastener or pin can extend through the hole1964. The fastener holds the lower bed 640 to the support arm 1942 whenthe bed 640 is in the upright position.

The bed 640 can be removed from the mounting member 1940 by removing thefastener or pin from the hole 1964 and sliding the bed 640 off thesupport arm 1942. The support arm 1942 can then be pivoted downward orremoved from the moving member 1920.

It should be appreciated that the upper bed 641 can be coupled to thelifting assemblies 630 in a similar manner. For example, the upper bed641 can be held in place by a fastener that extends through the hole1964 at the distal end of the support arm 1942.

FIGS. 26-27 show another embodiment of the mounting member 1941. Thisembodiment is the same as the mounting member 1940 except the supportarm and the support base do not rotate relative to each other. They arefixed in a stationary position relative to each other.

It should be appreciated that although FIGS. 1-6 show the lower bed 640support by the mounting members 1940 and the upper bed 641 supported bymounting members 1941, any combination of the mounting members 1940,1941 can be used. For example, the lower bed 640 can be supported by themounting members 1941, or the upper bed 641 can be supported by themounting members 1940.

FIGS. 27-35 show another embodiment of the mounting member 1840 and themoving member 1620. In this embodiment, the mounting member 1840 isvertically offset or dog-legged to allow the bed 640 to be lowered to asuitable height for a user to sit on but still have the guide member 618be far enough off the floor to not interfere with the wheels of off-roadvehicles and the like (FIGS. 27-30). In one embodiment, the guide member618 is at least 12 inches from the floor, at least 15 inches from thefloor, at least 17 inches from the floor, or at least 18 inches from thefloor.

In one embodiment, the top surface of the bed 640 is at least 15 inchesfrom the floor, at least 18 inches from the floor, or at least 20 inchesfrom the floor when the bed 640 is in the lowered or use position. Inthe same embodiment, the top surface of the bed 640 is no more than 24inches from the floor or no more than 29 inches from the floor when thebed 640 is in the lowered position.

The mounting member 1840 can be coupled to the moving member 1620 in aneasily releasable manner as described above. However, in thisembodiment, only the upper portion of the mounting member 1840 isconfigured to be coupled to the moving member 1620. Also, the length ofthe moving member 1620 has been reduced relative to the moving member1920.

The mounting member 1840 is especially suitable for use with theconfigurations of the bed 640 shown in FIGS. 136 and 256-260 of the '545patent. In both situations, the mounting member 1840 is capable ofholding the weight of the lower bed 640 so it is unnecessary to use thesupport legs 588, 1528 to support the beds 640 in the seatingconfiguration. It should be appreciated, however, that support legs canbe used to support the lower bed 640 in the lowered position.

The mounting member 1840 includes a main bracket 1846 coupled to asupport bracket 1842. Each side of the support bracket 1842 is coupledto a wheel 1844. The wheels 1844 ride on a guide track 1660 coupled tothe walls 16, 18 of the vehicle 10. The wheels 1844 provide the requiredsupport to prevent the mounting member 1840 from sagging when multipleusers sit on the lower bed 640 when it is in the seating configurationshown in FIG. 30.

The guide track 1660 can be any suitable material such as steel or thelike. The guide track 1660 prevents the walls 16, 18 from being damagedby the repeated motion of the wheels 1844 as the bed 640 is raised andlowered. In one embodiment, the guide track 1660 is provided as anintegral part of the lifting assembly 630. For example, the guide track1660 can be coupled to the rear side of the guide member 618.

Referring to FIG. 32, the mounting member 1840 supports the lower bed640 at location 1693, which is the top of the support arm portion of themain bracket 1846. The mounting member 1840 is coupled to the movingmember 1620 with the lowest point being at location 1691. It should benoted that the lowest point where the mounting member 1840 is coupled tothe moving member 1620 refers to a point of attachment not merelycontact.

As shown in FIG. 32, the location 1693 where the mounting member 1840supports the lower bed 640 is below the location 1691, which is thelowest point where the mounting member 1840 is coupled to the movingmember 1620, and below the bottom of the guide member 618.

It should be appreciated the various mounting mechanisms and mountingmembers disclosed herein can be combined in various ways to createadditional configurations. For example, the mounting member 1940 can bevertically offset using wheels or rollers as disclosed in FIGS. 27-35.Any combination of the enclosed subject matter is contemplated.

Additional Considerations

It should be noted that for purposes of this disclosure, the term“coupled” means the joining of two members directly or indirectly to oneanother. Such joining may be stationary in nature or movable in nature.Such joining may be achieved with the two members or the two members andany additional intermediate members being integrally formed as a singleunitary body with one another or with the two members or the two membersand any additional intermediate member being attached to one another.Such joining may be permanent in nature or alternatively may beremovable or releasable in nature.

The term “coupled” also refers to joining that is permanent in nature orreleasable and/or removable in nature. Permanent joining refers tojoining the components together in a manner that is not capable of beingreversed or returned to the original condition. Releasable joiningrefers to joining the components together in a manner that is capable ofbeing reversed or returned to the original condition.

Releasable joining can be further categorized based on the difficulty ofreleasing the components and/or whether the components are released aspart of their ordinary operation and/or use. Readily or easilyreleasable joining refers to joining that can be readily, easily, and/orpromptly released with little or no difficulty or effort. Difficult orhard to release joining refers to joining that is difficult, hard, orarduous to release and/or requires substantial effort to release. Thejoining can be released or intended to be released as part of theordinary operation and/or use of the components or only in extraordinarysituations and/or circumstances. In the latter case, the joining can beintended to remain joined for a long, indefinite period until theextraordinary circumstances arise.

It should be appreciated that the components can be joined togetherusing any type of fastening method and/or fastener. The fastening methodrefers to the manner in which the components are joined. A fastener isgenerally a separate component used in a mechanical fastening method tomechanically join the components together. A list of examples offastening methods and/or fasteners are given below. The list is dividedaccording to whether the fastening method and/or fastener is generallypermanent, readily released, or difficult to release.

Examples of permanent fastening methods include welding, soldering,brazing, crimping, riveting, stapling, stitching, some types of nailing,some types of adhering, and some types of cementing. Examples ofpermanent fasteners include some types of nails, some types of dowelpins, most types of rivets, most types of staples, stitches, most typesof structural ties, and toggle bolts.

Examples of readily releasable fastening methods include clamping,pinning, clipping, latching, clasping, buttoning, zipping, buckling, andtying. Examples of readily releasable fasteners include snap fasteners,retainer rings, circlips, split pin, linchpins, R-pins, clevisfasteners, cotter pins, latches, hook and loop fasteners (VELCRO), hookand eye fasteners, push pins, clips, clasps, clamps, zip ties, zippers,buttons, buckles, split pin fasteners, interlocking tabs, tab and holeconnectors, and/or conformat fasteners.

Examples of difficult to release fastening methods include bolting,screwing, most types of threaded fastening, and some types of nailing.Examples of difficult to release fasteners include bolts, screws, mosttypes of threaded fasteners, some types of nails, some types of dowelpins, a few types of rivets, a few types of structural ties.

It should be appreciated that the fastening methods and fasteners arecategorized above based on their most common configurations and/orapplications. The fastening methods and fasteners can fall into othercategories or multiple categories depending on the specificconfiguration and/or application. For example, rope, string, wire,cable, chain, and the like can be permanent, readily releasable, ordifficult to release depending on the application.
